Brazilian researchers' finding that exercising in the evening reduces blood pressure more than in the morning can help health professionals choose the time of day for aerobic training depending on the type of anti-hypertensive drug they take.

A novel ribbon worm species was discovered as part of the Smithsonian Tropical Research Institute's Training in Tropical Taxonomy program in the Bocas del Toro archipelago in Panama

Researchers from six countries in the Americas explored bromeliad microcosms, showing how drought and flood affect the functioning of aquatic ecosystems, especially at the bottom of the food chain.

Brazilian researchers observed that in uninfected adipocytes, the hormone irisin altered the expression of genes that regulate ACE-2, which encodes a protein to which the virus binds in order to invade human cells.

A new paper in Frontiers in Plant Science reviews the 'Seeds for Needs' approach that combines farmers' knowledge of resilient crops with 'elite' varieties identified by scientists.

Analysis published in Scientific Reports is based on climate models for the mid-Pliocene period, which occurred 3 million years ago and shared characteristics with present-day warming.

Toxic protein inhibits cell wall synthesis in rival bacteria. Discovery helps explain how pathogens cause imbalances in established microbial communities and could pave the way to the development of novel anti-microbial compounds.

New research looks at the swimming and sinking kinematics of nine species of warm water pteropods (sea snails) to shed light on their ecology, predator-prey interactions, and vertical distributions. By using a high-speed stereophotogrammetry system, investigators were able to focus on how the shell shape, body geometry, and body size affect their swimming behavior from a fluid mechanics perspective, while image analysis and metabarcoding related swimming behaviors to night time and daytime vertical distributions.

Project led by researchers from Brazilian and American institutions will collect primary data during the pandemic to create a repository that will serve as a basis for future studies. The findings of the comparative analysis will be published in book form.

Preserving terrestrial biodiversity requires more ambitious land-conservation targets to be established and met. At the same time, 'bending the curve' on biodiversity loss needs more efficient food production, and healthier and less wasteful consumption and trade. If undertaken with 'unprecedented ambition and coordination,' these efforts provide an opportunity to reverse terrestrial biodiversity loss by 2050.
